Console output retained in char[] causes OutOfMemoryError

I've got an applet that keeps running out of memory. A heap dump analysis shows that the culprit is a char[] owned by the traceMsgQueueThread that contains the entire contents of the java console output. This grows over time as log messages are sent to the console until eventually the applet runs out of memory.

This only seems to occur for a handful of clients, and has been seen on various JREs from pre 1.5 to 1.6.0_10.
